What is the difference in these 2 video cards besides 1 being 2 faned and the other being 3 fans ?

what 2 video cards? You didn't provide a link or description of a 2nd card...

Correction, you're tying to run both? Why? This card has dual screen capability, you shouldn't need the other card at all.

I purchased the 140 mm, though I would assume they should be the same. the fans themselves are 3 pin if you are going to attach them directly to your motherboard but they also come with 3 pin to molex adapters (which I used) in order to connect them directly to the power supply. I was able to attach two fans in series to one of my power supplies molex strips.

One is Superclocked and for the money is better to get from EVGA IMHO... it will not make a WORLD of difference but EVGA Superclocked Edition still runs very cool and no extra power needed... and will give just ever so slightly smoother gameplay.... I almost always buy the EVGA Superclocks because the price isn't usually anymore and even SOMETIMES less than standard!!! Plus I dont' like to Overclock myself so the little extra that a product can be overclocked will come out of the boxed overclocked.

Are you asking about running two video cards in the same computer? A ddr3 card and this one? If that is what you're asking, the answer is not simple. It depends on a lot of factors such as the make and model of the other card and the motherboard you're putting them with.

No , this one can only have 2 fans same speed. If you want separate speeds you need Pwm splitter

Barely any difference. The Base Clock differences are 1046 MHz vs. 1072 MHz, and Boost Clock of 1111 vs. 1137. That's pretty much it except for the extra fan. You can still only SLI connect a total of two of these cards if that's of any interest to you. For space and cooling efficiency, I'd opt for a dual GPU board instead. It will save you a ton of room in your tower. These cards are beasts, but effective.

Richard, if you go to device manager you'll see that there are 2 video card. One for low power consumption and the 7970 for aplications that demand much more power such as games. I sugest you download latest version of ATI Catalyst and set up your video and power saving preferences. Also using that program you can safely oveclock you processor and start getting great performance. Dont know why it comes with power saving preferences when you first open the lap.

I'm not familiar with that video card. The power supply HAS 2 6 pin power connectors as well as lots of others.

The card will use the fans depending on the temperature. You can override the settings using the provided application or MSI Afterburner

I believe tghe only difference is one has a 3 pin fan connector while the other is a PWM fan

I was weary buying another card with two fans since my experience with the GTX 580 TI (with dual fans also) ran too noisy for my tastes. It was just a preference this time around. If I could have the chance to listen to the fans on the 780 first, then it may have set my mind at ease. The dual fans also blow the exhausted heat straight into your case so if your case is not vented enough, you'll have some heat issues. So far the single fan version has not given me any heat increases either on the card or in the case.

revision 1 The only difference is needing 1 8 pin and 1 6 pin(rev 1) vs needing 2 8 pin(Rev 2. 2 8 pins should give it more overclock headroom in theory.) either way it's a fantastic card:) Good luck.

I agree with the other two answers: I would choose one or the other. There's no real reason to use both of them. If one doesn't work for you, switch to the other. In any case, there shouldn't be any kind of system fan warning. Didn't happen to me on the 120mm, so I don't see why you'd get one. If you do, check the BIOS to see if you can find a way to turn off the warning. I don't know your BIOS, but I'd bet there's a fan control in there somewhere. Check that out.

only 1,but can install 3 given the right circumstances, most use 2 without issue though, all 3 are the larger size fans as well {120mm fan}

No more than 3. cards are used and 3 is overkill. Not worth the extra expense for the amount of increased performance too small of a increase . 2 cards is enought . This card does not scale well in a quad configuration and in some cases it makes FPS worse. The card is old now with only 2 gb of memory. Even with 3 cards in SLI you still have only 2 gb of memory. Get two cards
